OUR ORIGINAL AWARD-WINNING ISOTONIC ENERGY GEL
Designed to deliver a quick and convenient supply of great-tasting, easily digestible carbohydrate without the need for water, our GO Energy Isotonic Gel was the world's first and the winner of the Queen's Award for Enterprise. It continues to be a go-to energy source for elite athletes worldwide.
WHY YOU SHOULD USE GO ENERGY ISOTONIC GEL
When you need fast energy, our world-leading GO Energy Isotonic Gel delivers easy-to-digest carbohydrate that can be used as part of your fuelling strategy without the liquid volume that often leaves you feeling bloated and sluggish. The gel also comes in highly practical packaging designed to be easily carried in place of bulky sports bottles.
- High carbohydrate
- Improves performance
- Requires no additional water or fluid
- Light, compact, easy-to-carry packaging
THE SCIENCE BEHIND GO ISOTONIC ENERGY GEL
Our Performance Solutions team has developed our innovative GO Energy Isotonic Gel formula that enables the stomach to absorb it quickly and turn it into energy fast without the need for additional liquid to dilute it. This in turn enables the rapid replenishment of depleted glycogen stores.
- 22g of carbohydrate
- Fast-absorbed, easily digestible
- Truly isotonic formula
- Delays onset of fatigue
HOW AND WHEN TO USE GO ENERGY ISOTONIC GEL
Each GO Energy Isotonic Gel sachet contains 22 grams of carbohydrate. Depending on your sport or event, you should aim to consume 1-3+ gels every hour to reach a 60g-90g target intake. In some circumstances, such as cold weather, it may be necessary to consume more. Tear off the top of the packaging and squeeze the contents into your mouth as and when required.
- Consume directly from packaging
- Combine with other SiS energy supplements to hit hourly 60-90g carbohydrate intake
Benefits
Depleting your carbohydrate stores during exercise is one of the major causes of fatigue. Delivering additional carbohydrate during exercise is known to improve performance, race times and delay the onset of fatigue.
The Isotonic formula allows the gel to empty from the stomach quickly as no fluid needs to be drawn into your stomach to dilute the gel, providing fast energy. SiS GO Isotonic Energy Gels are highly practical and can easily be carried without the requirement for bulky bottles.

These are great. I was using another product which I liked but this one is better because its not too sweet and sticky. The other product I was using was very sticky I guess it has more sugar in it not good if you get it on your hands and gloves. The SIS gel is really easy to digest and this flavour is not sickly. I will be using this one in future I really like it.
